Introduction to the Linksys Voice System
The LVS is an affordable and feature-rich voice over IP (VoIP) telephone system that is designed
especially for small businesses. The LVS uses standard TCP/IP protocols and can provide global
connectivity through any Internet Telephony Service Provider (ITSP) that supports Session
Initiation Protocol (SIP).
At minimum, the LVS includes a SPA9000 IP PBX and one or more SPA900 series IP phones.
These devices are connected through a switch to a local area network. With an Internet
connection, the LVS can subscribe to ITSP services to take advantage of low calling rates. With
the optional SPA400, the LVS can connect to the Public Switched Telephone Network (PSTN) to
support legacy phone lines. Figure 1-1 illustrates the LVS Solution in a typical deployment.
